When building a computer, it is always nice to have a form factor to fit the mission of the computer or to show off how the computer looks by having a cool look. Air flow is also important as the major components of the computer often generate a lot of heat including the video card and the CPU. Airflow also reduces dust build up in the computer and determines what peripherals you can install in the case in terms of expansion and the number of case fans.
Cooler Master has always been the master of cooling computer equipment. Their line of High Air Flow cases has taken the concept of airflow to the next level with plenty of cooling fans and a size and ruggedness to take on all comers in the enthusiast market. Cool Master released the HAF 932 and 922 cases in the last two years. Today marks the launch of a new generation of HAF cases, with the release of the HAF X case which is on the review bench.
